The chart illustrates dilemma of human-machine control design:

• Absolute manual control often involves risks of inaccurate, slow task performance
• Full automation often fails to cope with exceptional situation, which might be unexpected

The HM control dilemma is about balancing manual control with automation. It is associated with a particular control tradeoff curve. It is represented by the point on the HM control tradeoff curve.

Resilience assurance techniques enable to push down the control tradeoff curve, thereof enhancing the resilience by both machine and operators' control.
